Austin Air HealthMate air purifier in Sandstone, front view

Product Description

The Austin Air HealthMate is the original medical-grade air purifier — a 4-stage HEPA and carbon system that clears dust, allergens, smoke, pet dander, and everyday odors from the air in your home. It pairs 60 sq. ft. of True Medical Grade HEPA with up to 15 lbs of activated carbon and mineral-based media, all inside a solid-steel body handcrafted in Buffalo, NY. Trusted by families, schools, and clinics since 1990.

Key Features

  • True Medical Grade HEPA (60 sq. ft.) — captures 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, mold spores, pet dander, and smoke.
  • Up to 15 lbs of activated carbon & mineral media — over 780 cubic inches of carbon and mineral-based filtration adsorb common household gases and odors.
  • 360° air intake draws air in from all sides for faster, whole-room cleaning.
  • 3-speed centrifugal fan moving up to 400 CFM on high, with a quiet <50 dB low setting.
  • Solid steel construction — no cheap plastic to off-gas; CSA approved.
  • Filter built to last up to 5 years under normal residential use, backed by a 5-year mechanical warranty and a 5-year prorated filter warranty.
  • Plugs into any standard 120V outlet and draws roughly 147 W at full speed.
  • Available in four colors — Sandstone, Midnight Blue, White, and Black.

4-Stage Filtration

  • Stage 1 — Large-particle pre-filter: dust, hair, and pet dander.
  • Stage 2 — Medium-particle pre-filter: mold, spores, and pollen.
  • Stage 3 — Activated carbon & mineral blend: over 780 cubic inches / up to 15 lbs for gases and odors.
  • Stage 4 — True Medical Grade HEPA: 60 sq. ft. for fine particles, smoke, and allergens.

Best For

  • Allergies, asthma, and sensitivity to dust and pollen
  • Pet dander and household odors
  • General smoke and particle removal in bedrooms, living rooms, offices, and classrooms
  • Everyday clean-air peace of mind in homes, workplaces, and schools

Need stronger protection against chemicals, VOCs, formaldehyde, and wildfire smoke? The HealthMate Plus adds potassium iodide impregnated carbon to this same platform for enhanced gas and chemical removal.
